LOPEZ, David et al. Clinical gait analysis in patient with poliomyelitis sequelae and total knee arthroplasty. Enfermería (Montevideo) [online]. 2021, vol.10, n.1, pp.75-88.  Epub 01-Jun-2021. ISSN 1688-8375.  https://doi.org/10.22235/ech.v10i1.2359.

Poliomyelitis is a disease that may cause irreversible sequelae, generating muscle strength deficits, flaccid paralysis and hyporeflexia, among others. Even though poliovirus infections are under control, people with sequelae that can affect their quality of life and everyday functions such as walking, are still being treated. When these sequelae affect the morphology and functionality of the knee joint, and every other conservative option has been exhausted, the total knee arthroplasty (TKA) is one of the most common surgical interventions. The main goal of the present study is to perform an instrumented gait analysis test of a patient with poliomyelitis sequelae and TKA, in order to define the best rehabilitation strategy and achieve the highest level possible of the patient’s function. 3D Gait Analysis was performed with an 8-camera motion capture system and reflective markers placed on specific body landmarks. Results show gait pattern disturbances in every joint and at every anatomical plane, being the most relevant the right hip internal rotation and a fixed 9 degrees ipsilateral knee flexion during the first half of the gait cycle. The analysis suggests that the patient adopts strategies that promote the activation of the tensor fascia lata as hip flexor and knee stabilizer at the maximum available extension (9 ° of flexion) replacing the weakened quadriceps muscle due to the poliomyelitis sequelae.
